Crop Residue Management (CRM): Turning Stubble into Sustainable Wealth

Crop Residue Management (CRM): Turning Stubble into Sustainable Wealth

Introduction

Crop Residue Management (CRM) has emerged as a key pillar of India's transition towards a circular economy in agriculture, where agricultural waste is treated as a resource rather than discarded as waste. With India generating nearly 350 million tonnes of agricultural waste annually, improper disposal through stubble burning contributes significantly to air pollution, greenhouse gas emissions, and soil degradation. CRM promotes sustainable management of crop residues through both in-situ and ex-situ approaches, transforming agricultural biomass into organic manure, bioenergy, and other value-added products.

Analysis

Crop residues such as straw, stalks, and stubble are generated after harvesting crops. While a portion is utilized as fodder, fuel, mulch, compost, or raw material for industries, a considerable amount is still burned in fields to quickly prepare land for the next crop cycle. This practice results in severe environmental consequences including deterioration of air quality, loss of soil nutrients, reduction in soil microbial activity, and increased greenhouse gas emissions.Recognizing these challenges, the Government of India launched the Crop Residue Management (CRM) Scheme to discourage open-field burning and encourage scientific management of residues. The programme promotes in-situ management, wherein crop residues are incorporated into the soil or used as surface mulch, thereby improving soil organic carbon, moisture retention, and nutrient availability. Simultaneously, ex-situ management encourages collection and utilization of residues for composting, bioenergy generation, compressed biogas (CBG), biomass-based power plants, and industrial applications.The CRM initiative has significantly expanded infrastructure and mechanization support. Between 2018-19 and 2025-26, the Government released ₹3,926.16 crore to Punjab, Haryana, Uttar Pradesh, NCT of Delhi, and ICAR for implementing crop residue management measures. During this period, more than 42,000 Custom Hiring Centres (CHCs) were established and over 3.24 lakh CRM machines were supplied to CHCs and individual farmers, enabling wider access to residue management technologies.The programme also complements broader waste-to-wealth initiatives such as GOBARdhan, which converts crop residues, cattle dung, and food waste into biogas and organic manure. Such integration supports the development of a circular agricultural ecosystem where waste is continuously reintegrated into productive use.Beyond environmental benefits, CRM contributes to soil health restoration, carbon sequestration, renewable energy generation, farmer income diversification, and climate resilience. It aligns with India's commitments towards sustainable agriculture, clean air, and resource-efficient growth.

Key Achievements under CRM

CRM and Circular Economy

CRM embodies the principles of the 6Rs of Circular Economy:

Static Part

Crop Residue Management (CRM) Scheme

In-Situ Management

• Residues retained in the field.
• Used as mulch or incorporated into soil.
• Enhances soil organic matter and moisture.

Ex-Situ Management

• Residues collected and transported.
• Utilized for:
  • Compost production
  • Biomass power generation
  • Compressed Biogas (CBG)
  • Biofuels
  • Industrial applications

Custom Hiring Centres (CHCs)

• Provide CRM machinery on rent to farmers.
• Improve accessibility of residue management equipment.
• Reduce capital burden on small and marginal farmers.

Challenges

• High transportation cost of biomass.
• Limited market linkages for crop residues.
• Lack of awareness among farmers.
• Short window between crop harvesting and sowing.
• Need for greater private sector participation in biomass utilization.

Way Forward

India's agricultural residues possess the potential to generate over 18,000 MW of power annually. Strengthening CRM through technological innovation, improved biomass supply chains, expansion of bioenergy infrastructure, and greater farmer participation can transform agricultural waste into a valuable economic resource. Integrating CRM with initiatives such as GOBARdhan, AIF, and AHIDF can further accelerate the transition towards a resilient, low-carbon, and circular agricultural economy.
